Diamond coating spalling can be prevented

Coating flaking is a serious problem of diamond coated tools, is also a common problem (especially in the processing of carbon fiber like material) will result in tool life are difficult to predict. The late 1990s, flap wheel,interfacial chemical characteristics were identified as important factors to affect the performance of the diamond coating adhesion. By selecting the good compatibility Carbide chemical characteristics, using the appropriate pretreatment technology and reasonable deposition reaction conditions, it is possible to reduce or eliminate the peeling of the diamond coating, and to stably achieve a smooth wear mode. Normal wear diamond coated tool is observed under the microscope, can be found, the diamond is stable wear until the cemented carbide substrate, without chipping or flaking.metal cutting wheel
